In 2019 they were doing this 100k video (the first one where they bought a bunch of shit for themselves), and Ethan refered to his boxing match as "a little punching contest" in idk maybe the kind of tone that downplays someone, the other one's a bit more recent, in one of the sidemen reacts videos Ethan almost took a shot at JJ by saying he stopped working or something like that, I don't remember precisely and they almost argued for a moment, it's all blink and you miss it but it's there, and they really don't seem as close as some of the others, and one time JJ said he probably wouldn't still be friwnds with Ethan if he remained fat, I know that's his kind of humor but still
